Abstract

The Seismic Experiment for Interior Structure (SEIS) of the InSight mission to Mars, has been providing direct information on Martian interior structure and dynamics of that planet since it landed. Compared to seismic recordings on Earth, ground motion measurements acquired by SEIS on Mars are made under dramatically different ambient noise conditions, but include idiosyncratic signals that arise from coupling between different InSight sensors and spacecraft components. This work is to synthesize what is known about these signal types, illustrate how they can manifest in waveforms and noise correlations, and present pitfalls in structural interpretations based on standard seismic analysis methods. We show that glitches, a type of prominent transient signal, can produce artifacts in ambient noise correlations. Sustained signals that vary in frequency, such as lander modes which are affected by variations in temperature and wind conditions over the course of the Martian Sol, can also contaminate ambient noise results. Therefore, both types of signals have the potential to bias interpretation in terms of subsurface layering. We illustrate that signal processing in the presence of identified nonseismic signals must be informed by an understanding of the underlying physical processes in order for high fidelity waveforms of ground motion to be extracted. While the origins of most idiosyncratic signals are well understood, the 2.4 Hz resonance remains debated and the literature does not contain an explanation of its fine spectral structure. Even though the selection of idiosyncratic signal types discussed in this paper may not be exhaustive, we provide guidance on best practices for enhancing the robustness of structural interpretations.

Abstract

Mars’s seismic activity and noise have been monitored since January 2019 by the seismometer of the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander. At night, Mars is extremely quiet; seismic noise is about 500 times lower than Earth’s microseismic noise at periods between 4 s and 30 s. The recorded seismic noise increases during the day due to ground deformations induced by convective atmospheric vortices and ground-transferred wind-generated lander noise. Here we constrain properties of the crust beneath InSight, using signals from atmospheric vortices and from the hammering of InSight’s Heat Flow and Physical Properties (HP) instrument, as well as the three largest Marsquakes detected as of September 2019. From receiver function analysis, we infer that the uppermost 8–11 km of the crust is highly altered and/or fractured. We measure the crustal diffusivity and intrinsic attenuation using multiscattering analysis and find that seismic attenuation is about three times larger than on the Moon, which suggests that the crust contains small amounts of volatiles.

Abstract

Therapeutic drug monitoring (TDM) is a multidisciplinary activity. Because laboratory reports are part of the patient's chart, some clinical information is required. In order to guarantee quality and safety, an increasing number of TDM departments have implemented a quality management system. The aim of the present article is to review the three phases of TDM: the pre-analytical, analytical and post-analytical phases. In the pre-analytical phase, it is necessary to acquire a valid specimen collected at the specific time window. Analytical methods should be validated, assessing possible interfering substances. The objective of the post-analytical phase is the final report, which should include correct interpretation, as well as possible advice. Appropriate pharmacokinetic interpretation avoids unnecessary costs and leads to clinical benefits. Clin Chem Lab Med 2010;48:437-46.

Abstract

The evaluation of the determination of plasmatic concentrations of theophylline (PCT) in clinical practice is scarce. An observational study was carried out with the aim of discerning the reasons why PCT determinations are requested, the theophyllinemias obtained and the attitude of the medical staff in a hospital.PCT determinations obtained in 113 patients over a period of 3 months were analyzed. Information concerning treatment and daily doses of theophylline, reasons for theophylline determination, apart from those included in the request for theophyllinemia determination, clinical history and treatment sheets were collected.Treatment with theophylline had been indicated in 78 patients (69%) with chronic bronchitis, and 30 (26%) with asthma. All the patients received medication in addition to theophylline. Daily dosage (SD) was 734 (260) mg and the daily doses as to body weight (SD) was 11 (4) mg/kg/day. 188 DNPT were performed, however 22 (12%) were inadequate; of the remaining 166 PCT determinations 117 (69%) had been requested with no indication of insufficient clinical response, suspicion of undesirable effects or modifying factors of the pharmacokinetics of theophylline. The mean plasmatic concentration (SD) was 11.3 (7) micrograms/ml. PCT was infratherapeutic in 74 PCT determinations (44%), therapeutic in 73 (44%) and toxic in 19 (11%). Therapeutic concentrations were obtained in only 16 (35%) of the 45 patients in whom a second PCT determination had been carried out.In this study scarce individualization in the indication of treatment and the doses of theophylline administered are observed. The reason for soliciting determination of theophyllinemia and dosage adjustment in terms of plasmatic concentrations are also commented upon.
